Hello, I wanted to know how I can do so that the 2 textboxes inserts the IDs this way in txt:
file.txt:
id|192919 <---- textbox1
id2|29b9a92 <---- textbox2
And then when you open the program again puts it like this in the textbox:
textbox1: 192919
textbox2: 29b9a92
I tried substring, split, but I'm doubtful because the numbers can vary when putting in the textbox, and to pick up I also do not know how it does because it varies. How can I do it? Thank you.
It's a bit confusing to ask, but to get the value after | . you can use split and pass index.
The split will make a array of strings , but if it has more than one | array will have a higher index.
string id1 = "id|192919";
string id2 = "id2|29b9a92";
string valor1 = id1.Split('|')[1];
string valor2 = id2.Split('|')[1];
If you have the possibility to have more than one | . You can use Substring next to IndexOf that will get the index of the first |
string id1 = "id|19291|9";
string id2 = "id2|29b9a9|2";
string valor1 = id1.Substring(id1.IndexOf("|") + 1);
string valor2 = id2.Substring(id2.IndexOf("|") + 1);
If your string always follows this standardization, split resolves. Use this method:
public static string GetId(string str)
{
var str1 = str.Split('|');
return str1[1];
}
To write to the file:
System.IO.File.WriteAllLines("arquivo.txt", new string[]
{
string.Format("{0}|{1}", textbox1.ID, textbox1.Text),
string.Format("{0}|{1}", textbox2.ID, textbox2.Text),
});
To read:
string[] linhas = System.IO.File.ReadAllLines("arquivo.txt");
foreach (string linha in linhas)
{
string[] separadores = new string[1] { "|" };
string[] tokens = linha.Split(separadores);
if (token.Length == 2)
{
string id = token[0];
string valor = token[1];
Func<string, System.Windows.Forms.Control, System.Windows.Forms.Control> getControle = (id, controle) =>
{
if (!string.IsNullOrEmpty(id))
{
if (controle.ID == id)
{
return controle;
}
if (controle.Controls != null && controle.Controls.Any())
{
foreach (var c in controle.Controls)
{
if (c.ID == id)
{
return c;
}
System.Windows.Forms.Control child;
child = getControle(c, id);
return child;
}
}
}
return null;
}
System.Windows.Forms.TextBox textbox = getControle(id, <seuform>) as System.Windows.Forms.TextBox;
if (textbox != null)
{
textbox.Text = valor;
}
}
}
